Abstract
The utility model relates to a double-station nitrogen spring life tester. In the tester, a hydraulic working station is connected with an oil tank; the oil tank is connected with a tester seat; a pressure variable pump is arranged in the hydraulic working station; the used oil cylinder is a double-head constant speed oil cylinder; and two nitrogen spring test pieces are placed at the two ends of a piston rod respectively to form an upper testing station and a lower testing station. In the tester, inner forces do work mutually when the testing pieces at the two stations are stretched, so the energy is fully utilized, and the energy consumption is reduced to the greatest extent; the working state of the nitrogen spring can be simulated to perform life test to be close to the actual working state so as to truly reflect a test result. The tester can simultaneously test two testing pieces so as to be favorable for result comparison and improve the testing efficiency.
Description
Technical field
The utility model relates to a kind of double nitrogen spring life test machine.
Background technology
The nitrogen spring life test machine all is single station at present, promptly places a nitrogen spring on the testing machine.The characteristics of nitrogen spring life test machine are, the pressure of required test is big during test, and frequency is fast, so the testing machine power demand is bigger.One Daepori leads to 10 tonnes of other nitrogen spring testing machines of model, needs the motor-driven of 30KW.To the standard stroke is that the nitrogen spring of 50mm requires more than 1,000,000 times in its in serviceable life, calculates by 30 times/minute, and testing the required working time is more than 600 hours, nearly 20,000 degree of power consumption.Experimentation cost is high.
Summary of the invention
The purpose of this utility model is: provide and designed the pressure variations pump in a kind of hydraulic workstation, oil cylinder is designed to double end constant speed oil cylinder, makes full use of the energy, can test the double nitrogen spring life test machine of two test specimens simultaneously.
It is achieved in that hydraulic workstation is connected with fuel tank, and oil cylinder is connected on the test support.Be provided with the pressure variations pump in the hydraulic workstation, oil cylinder adopts double end constant speed oil cylinder; Hydraulic oil pipe is connected with oil cylinder, hydraulic workstation and fuel tank; Two apparatus for adjusting position are separately fixed on the test support; Piston is fixed on the middle part of piston rod, and two nitrogen spring test specimens are placed on the two ends of piston rod respectively, forms upper and lower two test stations; Counter, control knob and travel switch are installed in the top of test support.
Advantage of the present utility model is: the internal force when utilizing the test specimen extension on two stations does work mutually, makes full use of the energy, reduces energy resource consumption to greatest extent; Can simulate the duty of nitrogen spring and carry out durability test, make it to be close, reflect test findings really with practical working situation.Can test two test specimens simultaneously, help result's contrast, and can improve test efficiency.

Embodiment
The utility model is connected hydraulic workstation 14 with fuel tank 13, oil cylinder 5 is connected on the test support 9.Be provided with pressure variations pump 15 in the hydraulic workstation 14, oil cylinder 5 adopts double end constant speed oil cylinder; Hydraulic oil pipe 11 is connected with oil cylinder 5, hydraulic workstation 14 and fuel tank 13; Apparatus for adjusting position 1,8 is fixed on the test support 9; Piston 10 is fixed on the middle part of piston rod 6, and nitrogen spring test specimen 2,7 is placed on the two ends of piston rod 6 respectively, forms upper and lower two test stations; Counter 3, control knob 4 and travel switch 12 are installed in the top of test support 9.
During the utility model work, 1, designed the pressure variations pump in the hydraulic workstation, when load is overweight, realize balance by reducing flow, thus the protection motor.2, oil cylinder design double end constant speed oil cylinder can be placed two nitrogen spring test specimens simultaneously and test.3, designed apparatus for adjusting position, length and stroke requirement according to test specimen cooperate the position of regulating test specimen with travel switch.4, design two electronic counters and count simultaneously, avoid error.Also can be used for simultaneously upper and lower station test specimen separately counts separately.By the travel switch image data, also play the reversing switch effect simultaneously.5, design control knob group is controlled the operation of testing machine and is stopped the manual and exchange automatically of realization.Manually be convenient to install and adjust test specimen, process of the test then adopts automatic operation.
